Parimal

The name sounds like an elite British country club brand, designed for lords hunting in the Scottish mist. But the truth is far more fierce. It was born in the suffocating, dripping darkness of a British prison cell, baptized in the fury of the Indian monsoon, & built by a family that refused to let an empire monopolize the sky. In the early 1910s, a brilliant 20 something Indian nationalist named Surendra Mohan Bose returned to Bengal. He was not an ordinary youth; he had traveled across the oceans, earning degrees in chemistry from Stanford & Berkeley. But instead of taking a lucrative job under the British Raj, he joined the underground Swadeshi movement. The British state quickly branded him a rebel. He was thrown into the bleak, damp cells of Hamirpur Jail. As the relentless monsoon battered the iron bars of his cell, Surendra watched a heartbreaking sight. Indian soldiers & postmen, forced to serve the colonial machine, were marching through torrential downpours with absolutely no protection. They were shivering, drenched to the bone, & coughing up blood from pneumonia. The British imported high-grade waterproof trench coats exclusively for European officers. To the Raj, Indian lives were cheaper than a yard of treated canvas. They had colonized the land, & now, they had monopolized the clouds. Behind those prison bars, listening to the thunder rattle his cell, Surendra swore a silent, burning oath: He would weaponize the rain. When he was finally released, Surendra did not have capital/a factory/blueprints. All he had was a chemist's brain & a fierce rage. In 1920, inside a cramped, suffocating outhouse on Nazar Ali Lane in South Calcutta, he huddled with his 3 brothers: Ajit, Jogendra, & Bishnupada. Their mission? To fuse raw rubber to cotton fabric to repel water. In the 1920s, working with raw rubber in the tropical heat of Bengal was a nightmare. The rubber would melt into a sticky, foul-smelling glue in July & crack like brittle glass in December. Day after day, the brothers inhaled toxic chemical fumes, blind-testing formulas on a makeshift boiling stove. Neighboring businesses mocked them. "The British have massive mills in Manchester," they sneered. "How can 4 Bengali boys in a shed stop the monsoon?" The brothers did not reply. They just stoked the fire. Finally, they perfected a secret, grueling vulcanization technique. They realized that if treated properly, water would roll off a human’s back exactly as it does from a duck’s oily feathers. They called it "The Duckback Process." In 1940, they formally incorporated as Bengal Waterproof Limited. They did not just sell rainwear; they slapped a defiant warning on every single box: "Entirely Indian... Indian capital, Indian labour, Indian materials, & Indian brain." When the 2nd World War broke out, the British military desperately needed waterproof gear for the jungle warfare in Burma. They looked around & realized the only factory capable of producing indestructible, tropical-grade waterproofs was Bengal Waterproof. The very empire that had jailed Surendra was now forced to beg his family for protection against the rain. For the next 50 yrs, Duckback became the literal armor of the Indian middle class. You could not navigate an Indian life w/o the distinct, heavy, comforting smell of a Duckback product. If your family went on a vacation on a steam-engine train, your mattress & pillows were rolled into a massive, rugged canvas Duckback Railway Holdall, strapped tight with thick leather belts. If a family member had a burning fever, a blue rubber Duckback ice-bag was placed on their forehead. & every June, millions of Indian children were packed off to school in heavy, dark-blue/Khaki Duckback raincoats with matching hoods. We walked to school looking like a marching army of shiny black beetles, completely impervious to the cloudbursts, smelling of industrial rubber and freedom. But as the 1990s bled into the 2000s, a silent tragedy struck. The Indian economy opened up. Cheap, feather-light, neon-colored nylon windbreakers & disposable plastic umbrellas from China flooded the streets. To a new generation, Duckback’s heavy, indestructible rubber looked archaic, clunky, & old-fashioned. The company slid into severe financial crisis, choked by debts. The pioneering Bose family eventually lost control of the empire they had built from a prison cell. Most iconic brands would have died there, buried in the graveyard of corporate history. But a brand born in a jail cell does not surrender to the passage of time. Duckback underwent a quiet, brilliant metamorphosis. They realized that while civilians wanted flimsy, colorful plastics, the protectors of the nation needed something that could survive hell. Today, reborn as Duckback India, the company has retreated from the flashy mall storefronts & gone deep into the shadows where it all began, the defense forces. Step into the high-altitude bases of Siachen/the secret naval docks of Vizag, & you will find Duckback. They are the ones manufacturing the pressurized G-suits for Indian Air Force fighter pilots, specialized submarine escape suits, & heavy-duty inflatable tactical boats for Navy commandos. They went back to the barracks to protect the soldiers Surendra Mohan Bose wept for a 100 yrs ago. Duckback did not survive because of foreign investment/Western machinery. It survived because 4 brothers were willing to inhale toxic fumes in a Calcutta shed, challenge the technological monopoly of the British Empire, & teach a colonized nation how to walk through a storm with their heads held high. The next time the sky turns the color of bruised iron & the power cuts out, listen closely to the rhythm of the raindrops hitting our window; for somewhere in the static of the storm, the phantom click of a vintage Duckback button is fastening itself, reminding us that long before we learned to run from the rain, an empire tried to drown us & we simply learned how to float.

In 1918, inside a dimly lit basement lab at the University of Calcutta, a young chemist was staring at a beaker of salt water. He did not have high-precision spectrographs/million-dollar grants from the Royal Society. He was working in a city choked by colonial taxes, using hand-blown glass tubes & flickering lanterns. His name was Jnan Chandra Ghosh. The greatest minds in Europe, including the legendary physical chemist Peter Debye, had spent decades trying to write a mathematical formula that could predict how strong electrolytes (salts) conduct electricity in a solution, & they had all failed. Ghosh sat down with a slate, threw out the existing European laws of thermodynamics, & introduced a radical new concept: The Anomaly of Strong Electrolytes. When he published his eqns, the absolute titans of global science: Max Planck, Walther Nernst, & Bragg were so stunned by the sheer accuracy of this unknown Bengali's math that they officially named the phenomenon 'The Ghosh Law/Theory'. But as the decades rolled on, European textbooks quietly repackaged his eqns, slapped Western names onto the formulas, & turned Jnan Chandra into a ghost. In the 1910s, a single batch at the University of Calcutta produced a terrifying concentration of genius. Jnan Chandra Ghosh, Meghnad Saha, & Satyendra Nath Bose (of the Bose-Einstein Condensate) were all classmates & roommates. They literally shared textbooks & lived on puffed rice (muri) because they were too poor to afford proper meals. During World War II, the global powers were desperate for oil. Nazi Germany was surviving purely because their scientists had figured out how to turn raw coal into synthetic liquid fuel (petrol) using the Fischer-Tropsch process. The exact chemical mechanism, however, was a heavily guarded military secret. Working out of the Indian Institute of Science (IISc) in Bangalore, Jnan Chandra Ghosh cracked the Nazi secret completely independently. He developed highly advanced, indigenous multi-component catalysts that could convert low-grade Indian coal into high-grade aviation fuel at a fraction of the cost. The British administration immediately classified his research during the war. They used his data to fuel allied aircraft, but when the war ended, the patents were subtly absorbed into international oil consortiums. Instead of being hailed as the man who gave India energy independence, his blueprints were filed away in govt archives to rot.3 Most people think the Indian Institutes of Technology (IITs) were designed by American/British consultants brought in by Nehru. In 1950, Nehru realized India needed an elite engineering nerve center. He did not call a foreign architect; he called Jnan Chandra Ghosh. Ghosh was the founding Director (1950-1954) of the Eastern Higher Technical Institute, which became IIT Kharagpur (India’s 1st IIT) in 1951. He was the man who literally walked through the old, abandoned Hijli Detention Camp (a former British prison for freedom fighters) & decided to build the 1st IIT on top of those exact prison grounds as a symbol of intellectual liberation. He designed the entire curriculum, set up the labs, & hired the 1st faculty. The moment IIT Kharagpur was running flawlessly, Ghosh packed his single suitcase, refused to take any lifetime pensions/administrative accolades, & quietly walked out to become the Vice-Chancellor of Calcutta University. He built the platform for India's entire modern tech boom, then vanished from its history. Jnan Chandra Ghosh is the ultimate ghost because he chose to be the scaffolding, never the monument. He fixed the math that mapped the stars for Saha, he engineered the catalysts that broke the Nazi fuel monopoly, & he literally built the very 1st IIT out of an old British prison camp. He sat in the same classrooms as Satyendra Nath Bose & shared food with Meghnad Saha, but while their names became immortal, Jnan Chandra chose to remain the invisible concrete beneath the structure of modern Indian science. Every time an IIT grad secures a million-dollar tech job today, they are standing on a stage built by a man who did not even leave his name on the curtain.

🎥With Ishwar’s Grace,I feel blessed to present CHAPTER-2 : ‘Fibonacci Speaks’. You will feel immensely proud ❗️ Just one hope- May the Next generation become aware of India’s immense contribution to the World of Maths🍿1/3

Decades before Docker and modern AI, Kolkata’s visionaries at Jadavpur University and the Indian Statistical Institute built ISIJU-1, a transistorized, second-generation machine commissioned in 1966, one of India’s first indigenous computers, conceived in 1961 for fast scientific computing.

The name sounds British, but it is actually a purely Indian acronym. In 1952, a 55 yr old grocery store owner from Nagpur named Keshav Vishnu Pendharkar decided to shut down his shop, pack up his family of 10 children, & move to Bombay. He wanted to create a chemical-free, swadeshi alternative to the foreign cosmetic brands that were ruling post-independence India. He started his business in a tiny, cramped godown in Parel, Bombay. He named his company after his father: Vishnu Industrial Chemical Company. V-I-C-C-O. There was no British Lord or foreign laboratory. It was just a middle-aged Marathi man & his sons working out of a shed with a dream to revive ancient texts. Keshav Pendharkar’s brother-in-law held a basic degree in Ayurveda. Together, they huddled over ancient scripts & formulated a tooth-cleaning powder made from 20 rare herbs & barks (including Babool, Bakul, & Neem).They called it Vajradanti. In the 1950s, urban Indians were rapidly switching to chemical, white, sweet-tasting toothpastes imported by MNCs like Colgate. When the Pendharkers tried to sell a brown, astringent Ayurvedic powder, shopkeepers laughed them out of their stores. Keshav & his sons refused to surrender. They literally walked the streets of Bombay, going door to door to hand out samples, educating people on how chemical foam was destroying their gums, & manually building their empire 1 household at a time. In 1971, Keshav passed away, & his son, Gajanan Pendharkar, took over. Gajanan looked at the skincare market & saw it was utterly dominated by colonial-legacy snow creams like Afghan Snow, Pond's, & Nivea. All of them were stark white. Gajanan decided to launch a face cream containing Turmeric (Haldi) & Sandalwood oil. When the product launched, shopkeepers panicked. They screamed, "Baap re! If women put this on their faces, it will turn them yellow!" Nobody wanted to buy a yellow cream because the world had been conditioned to believe that beauty products had to be white. The Pendharkars weaponized the traditional Indian wedding ritual of Haldi-Chandan. They sent salesmen into the markets armed with handheld mirrors. The salesmen would manually apply the cream onto the shopkeepers' faces right then & there to prove it absorbed completely into a vanishing base, leaving a glow w/o any yellow stains. If you remember the iconic jingle: "Vicco Turmeric, Nahi Cosmetic, Vicco Turmeric Ayurvedic Cream"... you should know that those words were not just a clever marketing tagline. They were a battle cry born from a massive legal warfare. In 1975, the Central Excise Department of India dropped a bombshell on Vicco. They insisted on classifying Vicco Turmeric & Vajradanti as "Cosmetics." If classified as cosmetics, the govt could levy a crippling 105% luxury tax on the products, which would have priced Vicco completely out of the market & forced them into bankruptcy. The Pendharkars refused to pay. They argued that their products were manufactured under a formal Drug License & were Ayurvedic Medicines (Drugs), which attracted significantly lower taxes. This was not a minor dispute; it turned into a historic, grueling 25 yr legal battle. The case climbed all the way up to the Supreme Court of India. While battling global giants in the market, the family spent their resources fighting their own govt in courtrooms for ~3 decades. Finally, in the 2000s, the Supreme Court ruled in favor of Vicco, legally decreeing that their products were indeed medicinal, cementing the truth of their tagline forever. How did a homegrown brand from a Parel godown become globally famous? Through sheer marketing brilliance before the internet existed. In the 1980s, South Asian immigrants abroad were obsessed with watching Bollywood movies on rented VHS video cassettes. Gajanan Pendharkar realized this & started buying ad space directly inside the video cassettes distributed globally. Long before foreign networks recognized Indian brands, families in the US, UK, & Middle East were singing along to the Vajradanti jingle before their favorite movie started. Despite controlling a multi-million dollar empire, the house had only 1 giant mega-kitchen. Every single meal was cooked in massive industrial-sized pots, & the entire family sat on the floor together to eat. Gajanan believed that if the family broke bread separately, the business would fracture into pieces. In the early decades, the sons & grandsons who worked for Vicco did not get individual corporate salaries/luxury allowances. The company took care of all household expenses centrally. If a family member needed a car/a dress/a medical trip, it was cleared by the family elders, ensuring that personal greed could never overtake the company's mission. Vicco did not survive because it was backed by British capital/Western tech. It survived because an Indian family was willing to go door to door with brown tooth powder, rub yellow cream onto skeptical faces, & spend 25 yrs in court defending the scientific validity of Ayurveda. The name might sound like a colonial legacy, but the blood inside the tube is Sampoorna Swadeshi.
